Nrrnn STATES F. Il. FURNISS, OF CLEVELAND, OHIO.

llVlPROVEIVlENT IN RAILROAD-CAR VENTILATORS.

Specication forming part of Letters Patent' No. 33,302, dated September17, 1861.

To all whom t may concern.-

Be it known that I, F. H. FURNISS, of Cleveland, in the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in Railroad-Car Ventilators; and I do hereby declare thatthe following is a full and complete description of the construction andoperation of the same, reference being had to the accompanying drawings,

l makinga part of this specication,in whiclr- Figure l is a perspectiveview. Fig. 2 represents the front end. Fig. 3 is a longitudinal verticalsection. Fig. 4c is a transverse vertical section.

The same letters of reference in the different views refer to likeparts.

The nature of my invention relates to an improvement in the mode ofVentilating cars, which consists of having the current of air producedby the rapid motion of the car or any other analogous way pass into aHaring mouth through a wind-wheel revolving it that is connected to ashaft, on which are a number of radiating arms and a perforated disk.The shaft and arms revolve in a case forming a water-chamber and areconstantly Wet, and the particles of dust in the air coming in contactwith them will adhere, and in this way the air will be cleansed from allimpurities when it passes down through an opening fresh and cool intothe car.

In the drawings, A represents the case, made of any suitable form andmaterial; B, the flaring mout-h attached to the front end of the case,and where the mouth opens into the case is arranged the wind-wheel O, asshown in Figs. 1, 2, and 3. To this wheel is connected the shaft D, thatis supported by the divisions E and F, in which it revolves.

a, Figs. 3 and 4, represents radiating arms, and h a perforated disksecured to the shaft, each row of arms alternating with the precedingrow, so that the air in passing through will come in contact with asmuch surface as possible.

E is a division fitting' closely to the inside of the case near theWind-wheel and extending up far enough to prevent the waterin thechamber from running out.

To the back end or division F of the case is attached the pipe or flueH, which opens into the car and connects with the inside of the case bythe chamber d through the opening c, as shown in Fig. 3.

As the current of air passes into the case it revolves the wheel O,turning the shaft, and comesin direct Contact with the radiatingarms,and as they revolve inla water-chamber they are kept constantly wet andthe dust in the air adheres to them, and as the arms are placedalternately with each other the port-ion of air that passes by one armwill strike the next, and so on, passing through the perforated disk b,the holes of which are dripping with water, when the air will beperfectly freed from all impurities. It then passes up through theopening c into the chamber (Z and down through the pipe I-I into the carfresh and pure, fit for breathing.

I is a bar placed across the pipe, through which screws the stem J thatraises and lowers the valve K, by means of which the amount of fresh airadmitted into the car can be regulated, as indicated by the dotted linesin Fig. 3. It also detiects the current of air and disseminates itequally over the car, so that there will be no current coming down inone particular place upon the heads of the passengers.

The case is placed on the top of the car, the mouth B opening in thedirection in which the train is moving.

L is a lid on the top of the case, by means of which the chamber issupplied with water.

With this arrangement the cars will be sufficiently and well ventilatedwith the doors and windows closed when the train is in niotion.

Vhat I claim as my improvement, and desire to secure by Letters Patent,is

l. The fan-wheel O, revolving the radiating arms ct, when combined withthe disk b and water-chamber, all arranged and operating substantiallyas described.

2. The gage-valve K and flue H, in combination with the Water-chamberand revolving arms u, and disk Z9, in the manner and for the purpose setforth.
